Genomic insights into the origin of farming in the ancient Near East
Open accessPublished version of a preprint
Abstract
We report genome-wide ancient DNA from 44 ancient Near Easterners ranging in time between ~12,000 and 1,400 bc, from Natufian hunter-gatherers to Bronze Age farmers. We show that the earliest populations of the Near East derived around half their ancestry from a 'Basal Eurasian' lineage that had little if any Neanderthal admixture and that separated from other non-African lineages before their separation from each other. The first farmers of the southern Levant (Israel and Jordan) and Zagros Mountains (Iran) were strongly genetically differentiated, and each descended from local hunter-gatherers. By the time of the Bronze Age, these two populations and Anatolian-related farmers had mixed with each other and with the hunter-gatherers of Europe to greatly reduce genetic differentiation. The impact of the Near Eastern farmers extended beyond the Near East: farmers related to those of Anatolia spread westward into Europe; farmers related to those of the Levant spread southward into East Africa; farmers related to those of Iran spread northward into the Eurasian steppe; and people related to both the early farmers of Iran and to the pastoralists of the Eurasian steppe spread eastward into South Asia.

TL;DR
Genome-wide ancient DNA from ancient Near Easterners shows that early populations had substantial “Basal Eurasian” ancestry with little if any Neanderthal admixture, and that the first farmers of the southern Levant and Zagros/Iran were strongly genetically differentiated and descended from local hunter-gatherers. Later admixture among these farmer populations and with European hunter-gatherers reduced West Eurasian genetic differentiation and spread Near Eastern-related ancestry into Europe, East Africa, the Eurasian steppe, and South Asia.
Key findings
- Basal Eurasian ancestry was pervasive in the ancient Near East, with highest estimates in Iran Mesolithic (66±13%), Iran Neolithic (48±6%), and Levant Epipaleolithic Natufians (44±8%). Basal Eurasian ancestry was negatively correlated with Neanderthal allele sharing; extrapolation gave Basal Eurasian Neanderthal ancestry at 9±26% relative to non-Basal Eurasians, with a 95% CI of −42 to 60%, truncated to 0–60%.
- The earliest West Eurasian populations were extremely differentiated: FST among the four “corners” of PCA was 0.08–0.15, comparable to 0.09–0.13 between present-day West Eurasians and Han. By the Bronze Age, differentiation had fallen to present-day levels, with FST ≤0.025 for 95% of West Eurasian population pairs and ≤0.046 for all pairs. Levantine farmers shared more alleles with Natufians than with Iran farmers (f4 Z=13.6), and Iran/Caucasus farmers shared more with local hunter-gatherers than with Levant farmers (Z>6).
- Levant first farmers traced ~2/3 of their ancestry to Natufian-related people and ~1/3 to Anatolian farmer-related people. Iran Chalcolithic-related ancestry contributed ~44% to Levantine Bronze Age, ~33% to Chalcolithic northwest Anatolians, and ~43% to early Bronze Age steppe populations. European early farmers were not directly descended from southern Levant farmers (f4 Z=15), and East African West Eurasian ancestry was better modelled by Levantine early farmers. In South Asia, ANI was modelled as a mix of Iran early farmer and Bronze Age steppe ancestry; Mala had ~18% steppe-related ancestry and Kalash ~50%. ANE ancestry ranged from ~40% in Native Americans to no less than ~5–10% in diverse East Asian groups, with EHG deriving ~3/4 of ancestry from ANE.
Methods
- The study generated genome-wide ancient DNA from newly reported ancient Near Eastern individuals dating ~12,000–1,400 BCE from the southern Caucasus (Armenia), northwestern Anatolia, Iran, and the southern Levant. The abstract reports 44 ancient Near Easterners; the main text reports genome-wide data passing quality control for 45 individuals, with median coverage of 172,819 SNPs and radiocarbon dates for 26 individuals (22 newly generated).
- DNA was extracted mainly from the inner-ear petrous bone, converted into barcoded libraries, and enriched by in-solution hybridization for ~1.2 million SNP targets. The new data were merged with previously published ancient data to form a dataset of 281 ancient individuals and with 2,583 present-day people genotyped on the Affymetrix Human Origins array (238 newly genotyped).
- Analyses included PCA, ADMIXTURE, outgroup f3, f4-statistics, qpAdm, qpWave, qpGraph, FST estimation, and a ghost-population cline-intersection method; ancient individuals were represented in pseudo-haploid form.
Limitations
- Stated: poor DNA preservation in warm climates had previously made it impossible to study the first farmers; the authors could not test for a link to present-day North Africans; the spatial distribution of Anatolian/European-like farmer populations is unknown, so an Anatolian origin of European farming cannot be exclusively proven; one individual had a radiocarbon date inconsistent with its archaeological context and was also a genetic outlier.
- Stated: the authors were concerned that conclusions might be biased by which populations happened to be sampled, and they tested robustness by withholding major populations and using ghost-population modelling.
- Evident from the text: sampling is uneven across time and geography, many key ancient populations are unsampled or inferred as “ghosts,” and several conclusions depend on qpAdm/qpWave/qpGraph models and the available reference populations.

The relative homogeneity of present-day West Eurasians reflects extensive migration and admixture that homogenized geographically and genetically disparate sources of ancestry.
“The relative homogeneity of present-day West Eurasians in a world context2 suggests the possibility of extensive migration and admixture that homogenized geographically and genetically disparate sources of ancestry.”

The spread of the world's first farmers from the Near East was a mechanism for homogenizing West Eurasian ancestry.
“The spread of the world's first farmers from the Near East would have been a mechanism for such homogenization.”

The qpAdm/f4 reference populations used in the analyses are appropriate proxies for the ancestral populations they represent.
“We used qpAdm7 to estimate Basal Eurasian ancestry in each Test population.”
“We used this approach to carry out a systematic survey of ancient West Eurasian populations to explore their possible sources of admixture (Fig. 4; Supplementary Information, section 7).”
The authors state this as an assumption.
Basal Eurasians had no less Neanderthal admixture than Mbuti from sub-Saharan Africa.
“We truncated to 0-60% on the assumption that Basal Eurasians had no less Neanderthal admixture than Mbuti from sub-Saharan Africa.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-26, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-26 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
